Ace Referee is a companion application for handball, racquetball and squash referees. The application is available for devices running Android and iOS software. Ace Referee replaces the referees scoring card, but does much more. It has timers for timeouts, equipment timeouts and game intermissions. It keeps track of who serves in each game and for doubles matches it manages both side outs and half outs. Arguably the most attractive feature of Ace Referee is its live score capability.
